Thread: python - be: Fix a bug with send method invocations on iterators.

Log Message:
-----------
Fix a bug with send method invocations on iterators.

The returned object was not being coerced through the call's output. This leads
to the attempt to get a type cache entry on an arbitrary python type. Of
course, only the Postgres types have the entries available, so this would
normally result in a pointer to an invalid memory address.
